Research on CBM information system architecture based on multi-dimensional operation and maintenance data

摘要

Condition Based Maintenance(CBM) is a preventive maintenance strategy based on the actual running state of equipment. There are some deficiencies in the implementation of traditional CBM method. Firstly, how to acquire data used by CBM reasonably and improve the data coverage of equipment information is a problem to be solved. Secondly, the CBM method is still a maintenance strategy, when facing the different types of data, how to manage these data with characteristics of multi-sources, heterogeneous and different time scales for convenient searching and data processing also need to be studied. At the same time, how to choose a reasonable model to deal with this data, and then quickly give the maintenance strategy to the staff is another problem. Above all, this paper presents an CBM information system architecture based on multi-dimensional operation and maintenance data, including extensible data acquisition method; data management method based on Ontology Modeling and data processing method based on model selection. The architecture proposed sets data acquisition, data management and data analysis in one system, effectively integrating available information and making the whole analysis process becomes simple, and shortening the analysis process and improving the efficiency of data analysis through computer technology and information technology.
